Got a problem with Async!

Question

Hey. I made a custom loadingscreen for my game but i got a problem:

List item

the loadingscreen last for 0.5 second or something like that so i cant see the "Facts" that i put on it and i want to make a "Press any key" button to load the new level after it is loaded 100%.

 void Update ()

{ StartCoroutine(DisplayLoadingScreen(levelToLoad)); }

 IEnumerator DisplayLoadingScreen(string level)
 {
     progress.enabled = true;
     fact.enabled = true;
     progressbar.enabled = true;
     know.enabled = true;
     background.enabled = true;

     progressbar.transform.localScale = new Vector3 (loadProgress,progressbar.transform.localScale.y,progressbar.transform.localScale.z);

     progress.text = "Loading Progress : " + loadProgress + "%";

         AsyncOperation async = Application.LoadLevelAsync (level);
         while(!async.isDone )
     {
         loadProgress = (int)(async.progress * 100);
         progress.text = "Loading Progress : " + loadProgress + "%";
         progressbar.transform.localScale = new Vector3 (async.progress, progressbar.transform.localScale.y, progressbar.transform.localScale.z);
         yield return null;

     }
 }

}

Ok so what i want to ask is: I have to put an if sentence to async or something like that If(async==is.Done && input.GetKeyDown("x")) Application.LoadLevel(level)

or something like that but it wont work because AsyncOperation async = Application.LoadLevelAsync (level); is gona load the level automatically when is 100%.

How should i do it?

You have to prevent Unity from switching to the new loaded scene by setting allowSceneActivation to false. Something like that:

 AsyncOperation async = Application.LoadLevelAsync (level);
 async.allowSceneActivation = false;
 while(!async.isDone || !Input.GetKeyDown("x"))
 {
     loadProgress = (int)(async.progress * 100);
     progress.text = "Loading Progress : " + loadProgress + "%";
     progressbar.transform.localScale = new Vector3 (async.progress, progressbar.transform.localScale.y, progressbar.transform.localScale.z);
     yield return null;
 }
 async.allowSceneActivation = true;

You might want to replace this ugly condition:

 while(!async.isDone || !Input.GetKeyDown("x"))

with

 while( !(async.isDone && Input.GetKeyDown("x")) )

by applying simply boolean logic ^^

Tnx for help but i manage to do it without allowSceneActivation. Now i dont know how to count how much %of the lvl load , it is always at 100%.

@Spoukey:
How you "managed" it without it? Also how large are your levels? If they aren't that heavy it probably loads too fast...
